All new speakers should be 'run in' to ensure they sound their best.
This is because the drive units are extremely stiff when new and require running time to loosen and move as they are intended.
Running in the speakers is simply the time that it takes for these units to loosen up, allowing the speaker to create a smoother and more pleasant sound with the correct amount of bass.
Speakers can be 'run in' in a couple of different ways:
- Run them face to face, millimetres apart, out of phase, playing music constantly for a couple of days. This is the quickest method but means that you don't have a system to enjoy for a few days.
- Just connect them to your system and use them normally. This will take longer but you don't have the inconvenience of a few days without a system to listen to. Usually, the speakers will be sufficiently run in after a total of 20-30 hours of normal use. They will then continue to develop and improve for the first hundred or so hours of use.
When running the speakers in as in option 1, we recommend running them out of phase, facing each other as the overall noise output is lower. This is because the phase reversal ensures each speaker cancels out much of the other's sound, so you can turn the system up louder to really get the drive units moving and run-in quicker.
Ultimately, it's up to you which option you choose - the end result will be the same.
Please note: As the drive units are quite stiff/inflexible to begin with, running extremely high volumes through them for the first 10 hours is not advised.
